Patent attributes
A fitting for a fluidic coupling includes a tube assembly that includes an inner tube, an intermediate tube formed of a polymeric material and disposed over at least a portion of a length of the inner tube, and an outer tube formed of a metal and disposed over the intermediate tube. The inner tube has an inner tube endface and a first fluid channel. The intermediate tube includes an extruded portion having a length and an intermediate tube endface. The outer tube has an outer tube endface and an outer surface. First and second radial crimps are formed on the outer surface at first and second distances from the outer tube endface and extend for first and second axial lengths, respectively. The inner and outer tube endfaces are co-planar and the intermediate tube endface is separated from the inner and outer tube endfaces by the length of the extruded portion.
